I have been Sous Vide cooking for a while using a Paragon. While it worked just as well as this one it required a lot of space to store. This new Joule is smaller than I imagined and it really gets the water to temp quick. I purchased the LIPAVI container and tailored lid...they fit like a glove! I like Sous Vide since it only takes 5 minutes to set up and 5 minutes to clean up everything when done...does not disrupt my workflow and I eat better...win win!Just dropped in a Flat Iron steak...mouth watering already.

Update:Just purchased a second one so I can do steaks at two different temps...these things ROCK!

Edited 5/3/17:I have changed my review for this product from 4 to 5 stars due to the extensive support Chefsteps has provided for Joule, including frequent and substantial updates to the app that have improved functionality and reliability. Shortly after my original review, Chefsteps released a firmware update for Joule. I have not experienced any unexpected device shutdowns since then, and the connectivity seems to have markedly improved. I still believe that buyers should explore the full range of sous vide options out there to separate the technique from the product, as there are several competitive sous vide devices on the market worth considering. I am thoroughly pleased with my purchase.

Original review:As many other reviewers, I was among the early adopters and received my Joule several months ago after a lengthy waiting period and significant delays. Looking at the other reviews, I would caution potential buyers to consider how much of each review is actually a review of Joule as a product, rather than a review of sous vide cooking as a convenient technique. The same goes for Joule’s marketing. Sous vide is awesome: it can be convenient, it offers precision and guaranteed results where traditional methods can be tricky (making hollandaise, achieving perfect doneness in meats, etc.), and it opens the door to a lot of fun experimenting in the kitchen. In my case, I buy a lot of meat in bulk to freeze, and also prepare and freeze a lot of foods. Coming home from work and throwing a frozen vacuum-sealed steak in a pot to cook perfectly via sous vide is incredibly satisfying. A quick sear and some pre-made sides from the fridge can have my family well-fed with only minutes of actual effort. All of that is the product of sous vide, though, and there are several competitive products on the market to consider.

As far as Joule itself goes (I have not used any other sous vide devices myself), my experience has been almost entirely positive. It heats fast, the temps are very accurate, it is quiet, it takes up very little space in the kitchen, I can fit it on almost any pot or container, and it generally does what it is supposed to do. The biggest drawback buyers discussed when Joule was in production was the lack of manual controls or display on the device. Everything is controlled via Joule's app, which I use on my cell phone. The app itself is great. Chefsteps has taken the production quality they are known for and really put it on display in the app. The recipes and guides included were fairly limited on release, but I have faith the library will continue to grow as Joule continues to sell.

My only problem with Joule thus far, and it might be more than a minor irritation for some, is the device losing sync with my phone on several occasions. I believe Joule is supposed to keep running and maintain its temperature when it loses pairing to the device controlling it, and it has done that every time I lost connection to it except one. Typically I use Joule for quick protein cooks, 1-2 hours with steak or pork chops, etc. In those instances I leave the phone plugged in on the counter across from Joule and check it periodically. Most cooks go without issue, but maybe one in three or four uses I will pop downstairs to check the app and it will be disconnected from Joule and unable to reconnect immediately. Most of the time it reconnects eventually, but I have finished a few meals without being able to reconnect (and trying regularly for an hour or so). In those cases it is frustrating to have no controls or readings on the device. It is not too difficult to drop in a probe thermometer with a temperature alarm, but having to monitor it takes away some of the convenience of sous vide. Only once have I experienced Joule shutting off in one of these situations. Fortunately I had been keeping an eye on the food and it came out fine, but there was no indication or warning that would have alerted me otherwise. It could have been a much more frustrating experience.

That said, I have completed a few dozen cooks with Joule, ranging from an hour to 36 hours. During 24 and 36 hour cooks I have let Joule run through the night, spent the day at work cautiously peeking at the app from time to time, and never experienced a single issue. I love my Joule, and I trust Chefsteps as a company. Based on my experience I would rate Joule as a 4.5 if Amazon would allow it, but I think the flood of 5 star reviews might be focusing too much on sous vide itself. I think a lot of the early reviewers are also early adopters that are probably also long-time followers and supporters of Chefsteps (as I am). I know there are many happy purchasers of competing sous vide devices, so potential buyers should consider the alternatives as well (J. Kenji López-Alt of Food Lab and Serious Eats fame has a thorough Joule review and comparison worth reading). With this being an entirely new device, and seemingly the company's first foray into manufacturing, the longevity and warranty of the device may also be something for new buyers to research in the future.

Had I never experienced Joule shutting off, I would probably rate it at a 5 despite the periodic lost connections. Having researched other devices on the market thoroughly before purchasing Joule, I can say that I have no regrets in buying it. If I ever purchase a second sous vide device, I may try one of the competing products (currently two Joules cannot be paired to the same device), but Joule would still be my first choice if purchasing a sous vide device for the first time.

Cons of Sous Vide cooking* Some people don't use Sous Vide and you'll have eat it anyway, and pretend to like it.* You'll have more time for cocktails while prepping dinner, which can get expensive

PROS vs. other Sous Vide devices* Significantly smaller than anything else on the market* The most powerful immersion circulator without paying for a pro model* App makes it dead simple to use with picture guides, allowing you to pick what you want your finished product to look like by pictures* Build quality - The fit and finish feels like something designed by Apple.* It will attempt to resume after power failure. Sansaire and Anova have no resume functionality, if you have a power outage or surge, you can end up ruining a cook. The Joule attempts to save the day!

CONS vs Other Sous Vide devices* No display. You can't look at it and know the temp, or set the temp from the device. This is a very minor drawback. No you can't look at the device in your kitchen to determine the current temp like I can with my Sansaire. But I no longer have to go into the kitchen to check on it. I don't even have to go into my home to check on it. I can do so from the grocery store while picking up more supplies since Aunt Helen is now gluten free apparently. Might want to pick up some more wine while you're there, apparently Tammy has hit a rough patch with Mitch but is bringing him to dinner anyway.
